Standard Ignition TS-374 Engine Coolant Temperature Sender

Engine Coolant Temperature Sender for Gauge Applications

Standard Ignition TS-374 is an engine coolant temperature sender built for vehicles that use a dashboard gauge or temperature indicator light. It features a screw-in design with a 3/8-18 thread, a brass finish, and a single male round connector for straightforward replacement in the correct application.

Fits 1985-1996 Ford Mustang, fits engines with gauges; fits 1986-1996 Ford Ranger, fits engines with gauges; and fits 1994-1996 Ford F-150, with gauge. This Standard Ignition TS-374 coolant temperature sender is also used in select Ford E-350 Econoline, Mercury Cougar, and Mercury Topaz applications.

Key Features

• Screw-in engine coolant temperature sender
• 3/8-18 threaded end for the listed applications
• Single male connector with round connector shape
• Brass finish for durable service use
• Factory-calibrated and tested for specified switch actuation
• Uses a formed bimetal contact arm for precise electrical contact movement

Detailed Description

Standard Ignition TS-374 is designed for coolant temperature monitoring in gauge-equipped vehicles and temperature indicator light applications. The sender uses a calibrated thermal switching design with a wax-based actuation system and bimetal contact movement to transfer the electrical signal at the specified temperature point. That makes it a direct-fit choice for service work where accurate gauge response matters.

Vehicle coverage includes Ford Mustang, Ford Ranger, Ford F-150, Ford F-250, Ford F-350, Ford E-350 Econoline, and related Mercury applications listed in the fitment data. If you are replacing a worn coolant temp sender on a gauge-equipped Ford truck or car, TS-374 provides the correct thread size, connector style, and mounting method for the listed vehicles.

This part cross-references Walker Products 214-1009 for the same application.

What It Helps Fix

• Inaccurate or erratic coolant temperature gauge readings
• Temperature warning light staying on or not activating correctly
• Failed sender signal to the instrument cluster or fan controller circuit
• Hard-to-diagnose overheating indication issues caused by a faulty sender
• Replacement needs on gauge-equipped Ford and Mercury applications

Installation Notes and Tips

Verify the vehicle uses a gauge or temperature indicator light application before ordering. Match the 3/8-18 thread size, screw-in mounting style, and single male connector to the original part. Clean the threaded port before installation and confirm the connector seats securely after tightening.

For best results, compare the original sender length and connector style with the part listing, especially on Ford F-150, F-250, and F-350 applications noted as gauge-equipped or water-pump mounted.

Quality Assurance

Standard Ignition manufactures this sender with controlled materials, factory calibration, and testing to confirm actuation at the specified temperature. As an OE-focused ignition manufacturer, Standard Ignition maintains quality control from component production through final assembly.
